The family of Morgan Stanley International bank chairman Jonathan Bloomer and his wife Judy on Thursday described them as "incredible people and an inspiration to many" following their deaths in the sinking of a luxury yacht in Sicily.
It came as Italian authorities continued to search in the wreckage for the 18-year-old daughter of tech tycoon Mike Lynch.
Mr Lynch was among five people whose bodies have been recovered from the wreck of the Bayesian, which capsized during a tornado early on Monday morning.
In a statement, Mr and Mrs Bloomer’s family said: "We are grieving for our loved ones and all of those affected by the tragedy.
"We would like to express our sincere gratitude to the emergency services and everyone who helped tirelessly in this rescue operation.
"Our parents were incredible people and an inspiration to many, but first and foremost they were focused on and loved their family and spending time with their new grandchildren.
"Together for five decades, our only comfort is that they are still together now. This is an unimaginable grief to shoulder. Our only ask is that our family's privacy is respected at this time."
Tributes have also poured in from across the tech and business worlds for Mr Lynch, describing him as a “pioneer” and a “giant of a man”.
A major search operation has been underway for the six missing people since the Bayesian sank in a storm off the coast of Sicily around 5am on Monday.Four of the missing were found dead on the wreck yesterday and brought to shore, while a fifth was recovered shortly after the search operation resumed this morning.
